SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

The skill provides a structured blueprint for engineers to design, implement, and document modern, accessible, and composable UI components, ensuring consistency across teams and design systems.

Core Features & Use Cases

  • Composable architecture: promotes splitting UI into Root, Item, Trigger, and Content components to improve reuse and maintainability.
  • Accessibility-first patterns: emphasizes ARIA roles, keyboard navigation, focus management, and semantic HTML to build inclusive components.
  • Design tokens and theming: guides token-driven styling and theming integration, enabling easy branding and theming across apps.
  • Publishing readiness and DX: covers documentation, naming conventions, and integration with registries or npm-like distributions.

Quick Start

Create a new UI component following the Root/Item/Trigger/Content pattern and apply accessible, token-driven design from this guide.

FAQPage Schema
How do I build accessible and composable UI components?

To build accessible and composable UI components, split your UI into Root, Item, Trigger, and Content primitives. This approach maintains semantic HTML, ARIA roles, and keyboard navigation while keeping components highly reusable and maintainable across teams.

What is the Root/Item/Trigger/Content pattern in component design?

The Root/Item/Trigger/Content pattern is a composable architecture that separates UI concerns into distinct primitives. It improves reuse and maintainability by allowing developers to assemble complex, accessible interfaces from small, focused building blocks.

How do I implement design tokens and theming for a UI component library?

Implement design tokens and theming by applying token-driven styling to your components. This approach decouples visual properties from component logic, enabling easy branding and consistent theme integration across multiple applications.

Does this component building guide work for framework-agnostic libraries?

Yes, this guide is explicitly framework-agnostic. It provides universal patterns for composable architecture, accessibility, and design tokens that can be applied regardless of the specific JavaScript framework or rendering engine you choose.

What's the best way to document UI components for developer experience?

The best way to document UI components is to follow DX-focused best practices, including clear naming conventions, usage examples, and data attribute documentation. This ensures engineers can easily integrate and consume your published components.

How do I prepare a UI component library for publishing to npm?

Prepare a UI component library for publishing to npm by establishing clear naming conventions, writing comprehensive DX-focused documentation, and ensuring your composable primitives are properly bundled for registry distribution.
